Mark 10:37 - Is it
in the new Jerusalem on earth or in heaven when the two disciples asked Jesus to be seated
on his right and left in his glory?

Mark 10:32-41 says, "And they were in the way
going up to Jerusalem; and Jesus went before them: and they were amazed; and as they
followed, they were afraid. And he took again the twelve, and began to tell them what
things should happen unto him, Saying, Behold, we go up to Jerusalem; and the Son
of man shall be delivered unto the chief priests, and unto the scribes; and they shall
condemn him to death, and shall deliver him to the Gentiles: And they shall mock him, and
shall scourge him, and shall spit upon him, and shall kill him: and the third day he shall
rise again. And James and John, the sons of Zebedee, come unto him, saying, Master, we
would that thou shouldest do for us whatsoever we shall desire. And he said unto them,
What would ye that I should do for you? They said unto him, Grant unto us that we may sit,
one on thy right hand, and the other on thy left hand, in thy glory. But Jesus said unto
them, Ye know not what ye ask: can ye drink of the cup that I drink of? and be baptized
with the baptism that I am baptized with? And they said unto him, We can. And Jesus said
unto them, Ye shall indeed drink of the cup that I drink of; and with the baptism that I
am baptized withal shall ye be baptized: But to sit on my right hand and on my left hand
is not mine to give; but it shall be given to them for whom it is prepared. And
when the ten heard it, they began to be much displeased with James and John."

If the
disciples had understood what Jesus had just told them, I would say that they were asking
about the Millennium. But it is very obvious that what Jesus was telling them about His
suffering, death, and resurrection, was somehow going right over their heads. In their
minds, that thought just could not seem to sink in as to what was going to happen. Notice
what Peter replied when Jesus started talking about these things in Matthew 16:21-23,
"From that time forth began Jesus to show unto his disciples, how that he must go
unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be
killed, and be raised again the third day. THEN PETER TOOK HIM, AND BEGAN TO REBUKE HIM,
SAYING, BE IT FAR FROM THEE, LORD: THIS SHALL NOT BE UNTO THEE. But he turned, and said
unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not
the things that be of God, but those that be of men."

At the
point in time in question, it seems that the disciples were looking for Jesus to set up
His kingdom very soon upon earth, and they wanted to be the first to ask for high
positions close to Him.
